Product specifications

Intended use

This ELISpot Flex kit is intended for the enumeration of cells secreting human IgG1 using the ELISpot assay. For research use only. Not for use in diagnostic procedures.

Serum/Plasma samples

With this kit, detection of antigen-specific IgG1 secreting B cells can be performed using coated antigen. If detection with biotinylated antigen is preferred, the plate should instead be coated with the subclass specific antibody.

For analysis of memory B cells, we recommend pre-stimulation with R848 and recombinant human IL-2 (both included)."

Product details

Product	ELISpot Flex: Human IgG1 (ALP)
Application	ELISpot
Analyte	IgG1
Reactivity	Human
Specificity	This kit is based on a matched pair of mAbs enabling specific detection of human IgG1.

Shipping and Storage

Shipping	Shipped at ambient temperature.
Storage	Store antibodies and enzyme conjugate at 4-8 °C upon receipt. R848 and IL-2 should be stored at -20 °C.
Shelf life	At least 18 months from date of receipt.

Performance

PBMC were pre-incubated in the presence or absence of R848 and recombinant IL-2. The cells were then washed, added into ELISpot wells (100,000 cells/well) and analyzed for the secretion of IgG1 (overnight incubation).

Analyte information

IgG1

Analyte description	Immunoglobulin G (IgG) is the most abundant immunoglobulin isotype in serum, making up approximately 80% of all serum Immunoglobulins. In humans, there are four subclasses of IgG with the highest serum concentrations of IgG1, followed by IgG2, IgG3, and IgG4. In mice, the IgG subclasses are defined as IgG1, IgG2a/c, IgG2b, and IgG3. IgG1 binds to Fc receptors with high affinity and may also activate the complement system.
Alternative names	Immunoglobulin G1, IgG1
Cell type	B cell
Gene ID	3500
